/**
 * Constructs a ShortBandedRaster with the given SampleModel,
 * DataBuffer, and parent.  DataBuffer must be a DataBufferUShort and
 * SampleModel must be of type BandedSampleModel.
 * When translated into the base Raster's
 * coordinate system, aRegion must be contained by the base Raster.
 * Origin is the coordinate in the new Raster's coordinate system of
 * the origin of the base Raster.  (The base Raster is the Raster's
 * ancestor which has no parent.)
 *
 * Note that this constructor should generally be called by other
 * constructors or create methods, it should not be used directly.
 * @param sampleModel     The SampleModel that specifies the layout.
 * @param dataBuffer      The DataBufferUShort that contains the image data.
 * @param aRegion         The Rectangle that specifies the image area.
 * @param origin          The Point that specifies the origin.
 * @param parent          The parent (if any) of this raster.
